Crataegus species (hawthorn) have been commonly used in traditional medicine,
especially for the treatment of congestive heart failure. Many studies
confirmed that they are rich in polyphenols, thus exhibiting strong
antioxidant activity, which contribute to the beneficial effects of hawthorn
on the cardiovascular system. In the market, there are many herbal medicinal
products based on hawthorn, which consumption as adjuvant therapy in
heart-related issues is supported by European Medicines Agency. Since there
is a global trend of making homemade herbal preparations, this study aimed to
compare whether there is a difference in polyphenol profile and antioxidant
potential between homemade and commercial ethanol extracts of hawthorn.
Polyphenol profile was evaluated by determination of total phenolic and
flavonoid contents, and by quantitative analysis of selected polyphenols by
LC-MS/MS. Antioxidant potential was examined by DPPH, FRAP, and lipid
peroxidation inhibition assays. The results of this study suggest that
homemade ethanol extracts of hawthorn flowers, leaves and fruits are just as
good source of polyphenols and antioxidants as commercial ones, and their
utilization should be supported. Furthermore, hawthorn extracts made of
leaves and flowers are better source of bioactive polyphenols and have higher
antioxidant activity compared with the same of fruits, regardless of the
method of preparation.
